Patented July 8, 1952 UNITED STATES PATENT OFFICE v 2,602,688 l g 1:HANDLE FOR BOXES chasm A. Brunk, Chico, Calif. Q Application March 6,1951, Serial No. 214,068

My invention relates to improvements in handles for boxes, particularlypastebOard and like boxes, such as are provided for containing anddispensing soap flakes and like detergent material and are easilycrushed and break open when handled by the housewife with wet hands.

The primary object of my invention is to provide a handle for such boxesconstructed to straddle the box at one edge thereof for grasping by thehousewife, or other person, in handling to keep the hands out of contactwith the box and thereby obviate brushing and mining the box by handlingwith wet hands.

Another object is to provide a handle for the purpose above set forthwhich is adjustable to straddle boxes of different sizesand which iseasily attached and detached and will interlock, when attached, with thesides of the box in a manner to prevent deforming the box while securelyholding the same against slipping in the handle.

Still another object is to provide a handle for the above purposes whichis adapted to be manufactured at a low cost and which is durable andwill not slip in the hands.

Other and subordinate objects, within the purview of my invention,together with the precise nature of my improvements will be readilyunderstood when the succeeding description and claims are read inconjunction with the drawing accompanying and forming part of thisspecification.

In said drawing:

Figure 1 is a view in perspective illustrating my improved handle, inthe preferred embodiment thereof, applied to a box;

Figure 2 is a fragmentary view in horizontal section taken on the line2-2 of I Figure 1 and drawn to a larger scale; and

Figure 3 is a composite view in perspective the hand grip angle platesdetached. I

Referring to the drawing by numerals, according to my invention, achannel shaped handle I for straddling one edge of a box 2 is providedcomprising a pair of hand grip angle plates 3, 4 each embodying a smoothfront section 5, and a serrated and toothed section 6. The sections 5, 6are preferably rectangular in shape.

The front sections 5 are slidably connected together in overlappingrelation for relative lateral adjustment to variably space the sidesections 6 apart for receiving boxes 2 of difierent sizes therebetween.For this purpose, the front section 5 of the plate 3 is provided at itsends with inturned channel guides 8 slidably receiving the ends of thefront section 5 of the plate 4.

. 3Claims. (01,294, 34)

' Means are provided for fastening the front sections 5 together, andhence the plates 3, 4, in adjusted relation comprising a bolt 9extending through a bolt hole ID in the front section 5 of the plate3and through a transverse slot il in the front'section5 of the plate 4,the bolt 9 being. provided at the outer side of the front section 5 ofthe plate 4 with a wing nut 12 thereon.

The bolt 9 is provided with a square portionv l3 fitting in the slot IIto prevent said bolt from turning in said slot. The following means areprovided for separating the side sections 6 of the plates 3, 4 when thefront plates 5 are unfastened. and for a purpose presently explained.This last means comprises a substantially C-shaped leaf spring l4suitably fixed intermediate its ends, as at I5, on one end of alongitudinally slotted bar [6 welded, as at l1, to the inner side of thefront section 5 of plate 4 with the slot 18 of said bar registering withthe before mentioned slot H and having the squared portion [3 of thebolt 9 slidably fitting therein. The ends of the spring l4 projectsufliciently beyond the free longitudinal edge I9 of the front section 5of plate 4 so that in any adjusted position of the front sections 5, andalso of the side sections 6, said ends will press outwardly against theplate 3 at the juncture of the sections 5, 6 of said plate 3.

Like angular prongs 20 extend inwardly from the side sections 6 of theplates 3, 4 for penetrating the sides of the box 2 when moved upwardlyof said sides.

The serrations on the sections 6 preferably take the form of bosses 2|especially designed to prevent a hand grasping said sections 6 fromslipping off the same.

Outwardly bulging, transversely rounded longitudinal corners 22 areprovided .on the plates 3, 4 at the juncture of the sections 5, 6 toprevent said plates at said corners from tearing or mutilatinglongitudinal corners of the box 2.

In attaching the described handle, the plates 3. 4 are adjusted, in themanner described, to loosely fit against the sides of the box 2 and saidhandle positioned downwardly of said box in straddling relation to oneedge wall 23 thereof. The side sections 5 are then pressed toward eachother, to enter the prongs 20 in the sides of the box and the handlethen slid upwardly of the box which causes the prongs to completelypierce the sides of the box and draw the side sections 6 against thesides of the box. At this point, it is explained, that the side sections6, at least, are formed of flexible metal so that the same may flextoward each,

other and such flexing is facilitated by the type of corners 22described. To detach the described handle, it is merely necessary toloosen the wing nut I2 whereupon the spring l4 will react, in a mannerwhich will now be clear, to separate the side sections 6 and withdrawthe prongs 23 out of the sides of the box 2. As shown in Figure 2, whenthe prongs 20 have fully entered the sides of the boxrz. the handle I issecurely fastened to the heir against casual displacement.

Any suitable material may be used in forming the plates 3, 4, forinstance tin, or a resilient.

plastic.

The foregoing will, it is believed, suflice to am part a clearunderstanding of my invention, without further explanation. Manifestly,the invention, as described, is susceptible of modification,

without departing from the inventive concept, and right is hereinreserved to such modifications as fall within the scope of the appendedclaims.

Having described my invention, what is claimed.

3.8 new is;

1. A handle of channel tape m1 straddling an edge of a box comprising apair of hand gripfang'le plates embodying front sections and sidesections;

sections and Withdraw said prongs when said plates are unfastened.

2. A handle according to claim 1 wherein said last-named means comprisesa spring mounted to the front section pf one plate and bearing out-Wardly against the ide plate of the other section.

. 3. A handle according to claim 1 wherein said last-named meanscomprises a G-shaped spring mounted to the front section of one platewith its ends bearingoutwardly against the side section.

oftheother plate. v H
